Access Point System Naming Convention
The Access Point's system name is used as its host name. In order to prevent Access Points with default
configurations from registering similar host names in DNS, the default system name of the Access Point is uniquely
generated. Access Points generate unique system names by appending the last 3 bytes of the Access Point's MAC
address to the default system name.
The system name must be compliant with the encoding rules for host name as per DNS RFC 1123. The DNS host
name encoding rules are:
•
Alphanumeric or hyphen characters are allowed.
•
The name cannot start or end with a hyphen.
•
The name cannot start with a digit.
•
The number of characters has to be 63 or less. (Currently the system name length is limited to 32 bytes).
Image upgrades could cause the system to boot with an older system name format that is not DNS compliant. To
prevent problems with dynamic DNS after an image upgrade, the system name will automatically be converted to a
DNS compliant system name.
The rules of conversion of older system names are:
•
If the length is greater than 63 then the string is truncated. (This will not happen since the system name is anyway
limited to 32 bytes)
•
All invalid characters at the beginning or end of the string are replaced with the character 'X'.
•
All other invalid characters are replaced with hyphens.
